Why is the check engine light on in my Ford S-Max?

I recently noticed that my check engine light has turned on in my Ford S-Max. What could be causing this and how can I fix it?

It could be a variety of reasons such as a faulty oxygen sensor or a loose gas cap. It's best to take your car to a trusted mechanic to diagnose and fix the issue.

I had the same issue with my Ford S-Max and it turned out to be a faulty catalytic converter. Don't ignore the check engine light, get it checked before it becomes a bigger issue.
